MACHINE FOR SHAVING SOUND-RECORDS.

Specification of Letters Patent.

Patented Aug. 8, 1905.

A plieatinn filed June 24,1903. Serial No 162,962.

T at whom, it may concern:

Be it known that 1, JOHN F. Orr, a citizen of the United States, residing at Orange, in

the county of Essex and State of New Jersey, have invented a certain new and useful Improvement in Machines for Shaving Sound- Records, of which the following is a specification.

My invention relates to machines for shaving phonographic cylinders or other soundrecords; and my objects are to provide a simple and compact device for the purpose, one capable of efficient, rapid, and perfect opera tion and wherein finally generation of dust, chips, and shavings of wax outside of the machine is overcome.

The improved machine has been designed particularly for use in establishments where a large number of records require to be shavedas, for instance, in offices using phonographs for commercial purposes.

Generally stated, the invention consists in providing a mandrel or other support for the record with a shaving-knife arranged to be moved into engagement with the record, means for rotating the mandrel or other sup port at a high speed, and a fan or blower for directing the wax, chips, shavings, or dust produced in operation, into a suitable receptacle for the purpose, from which they may be subsequently removed, all as will be more fully hereinafter described and claimed.

In order that the invention may be better understood, attention is directed to the accompanying drawings, forming part of this specification, and in Which- Figure 1 is a plan view of the complete machine with the operating-handle removed; Fig. 2, a front view, partly in section; Fig. 3, a section on the line 3 3 of Fig. 2looking toward the right; Fig. 4, a section on the line 4 4 of Fig. 2 looking toward the left, and Fig. 5 a sectional view on the line 5 5 of Fig. 3.

In all of the above views corresponding parts are represented by the same numerals of reference.

The box or cabinet 1 is formed with a horizontal partition 2, below which is a sliding drawer 3, having an outlet-opening 4, covered by a screen or gauze 5. This drawer is also provided with a vertical gauze or perforated partition 6, through which the air front bar 19.

passes from the fan and by which a consider able proportion of the larger shavings will be separated from the air.

Located over an opening in the top of the cabinet or case 1 is a plate 8, carrying the bearings for the operative parts. Mounted in bearings 9 9 on this plate is a shaft 10, which carries the mandrel 11, over which is inserted the record to be shaved. The free end of this mandrel is supported by an end bearing 12, carried by a pivoted gate 13 in the usual manner. Secured to uprights 14 on the plate 8 is a stationary back rod 15, on which is slidably mounted a sleeve 16. Secured to this sleeve by a clamping-screw 17 is an arm 18, which straddles the mandrel and slides at its front end along the usual A weight 20 or its equivalent may be carried by the front end of the arm 18, so as to keep the shaving-knife in its proper engagement with the record. This knife, as shown particularly in Fig. 3, is composed of a sapphire cutting-tool 21, carried 011 the end of a rod 22, passing through a split sleeve 23 and connected to a guidepin 24, working in an opening in said sleeve to prevent the shaving-knife from turning axially. The shaving-knife is locked in any desired. position of adjustment by a screw 25 for clamping the two portions of the split sleeve on the rod 22, said screw being operated by a finger-piece 26.

The mandrel 11 is rotated at a high speed by any suitable arrangement of power-transmission device. In the specific form of the invention illustrated I mount a main shaft 27 in bearings 28, depending from a plate 8, and engage a removable handle 29, with the shaft to rotate the latter. The shaft 27 carries a pulley 30, which through a belt 31 drives a small pulley 32 on a counter-shaft 33. This counter-shaft carries a pulley 34, (see Fig. 2,) which drives through a belt 35 to the small pulley36 on the mandrel-shaft 10.

In order to feed the shaving-knife lengthwise of the record to properly shave the same, I make use of a relatively coarse-threaded feed-screw 37, with which engages a feednut carried on a spring-arm 39, screwed to the sleeve 16. When the arm 18 is elevated to lift the shaving-knife from the record, the nut 38 will be disengaged from the feedscrew, so as to permit the shaving-knife to be slid back to its starting position. The movement of the arm 18 axially with respect to the back rod 15 is limited by a finger 40 engaging a shoulder 41 on the plate 8. The feed-screw 37 is rotated in any suitable wayas, for instance, by a belt 42, extending between pulleys 43 and 44 on the shaft 10 and feed-screw 37, respectively.

In order to dispose of chips, shavings, and wax dust in the operation of the device, I arrange an open trough 45 lengthwise of the mandrel 11 and immediately below the path of the shaving-knife. This trough at its lower end communicates with a conduit 46, leading to a small centrifugal fan 47, whose discharge-outlet 48 communicates with an opening in the partition 2 immediately behind the screen 6 in the drawer. The fan 47 in operation produces a suction immediately adjacent to the shaving-tool, so that any particles of wax removed thereby will be drawn into the fan and be discharged into the back portion of the drawer 3. The air escapes through the screens 5 and 6 and deposits the wax particles in the drawer, which can be cleaned out from time to time, as required. The fan 47 is operated in any suitable wayas, for instance, by a belt 49, extending between pulleys 50 and 51 on the lanshaft and counter-shaft 33, respectively.

In operation the record or blank to be shaved is placed on the mandrel 11 and the knife engaged therewith and locked tightly in place. The handle 29 is now turned so as to rotate the mandrel at a high speedsay about two thousand revolutions per minute whereby a very effective and perfect shaving operation will take place, as will be understood. In this operation all particles of wax will be sucked down and deposited in the drawer 3, so as to thereby overcome one of the most serious objections to shavingma chines as now constructed, since in such prior machines the particles of wax not only soon cover all the working parts, but become distributed throughout the room in which the shaving is effected.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

In a shaving-machine, the combination with a support for a sound-record or blank and a shaving-knife movable longitudinally with respect to said support, of means for rotating said support, a suction-tube comprising an inlet adjacent to the rotating support and knife and at least equal in width to the distance traveled by the knife, a receptacle, and a discharge to the atmosphere, a fan for creating an air-draft through said suctiontube, and a screen for preventing the escape to the atmosphere of particles drawn through the suction-tube into the receptacle, sub stantially as set forth.

This specification signed and witnessed this 22d day of June, 1903.
